Van't Hoff factor

Van't Hoff factor

It is the ratio between the actual concentration of particles produced and the concentration of a substance as calculated from its mass, when substance is dissolved.

  • For most non-electrolytes dissolved in water, the van't Hoff factor is 1.

  • For most ionic compounds dissolved in water, the van't Hoff factor is equal to the number of discrete ions in a formula unit of the substance.
